Subject: [PATCH 5.2 221/313] IB/mlx5: Free mpi in mp_slave mode
From: Danit Goldberg <danitg@...lanox.com>
commit 5d44adebbb7e785939df3db36ac360f5e8b73e44 upstream.
ib_add_slave_port() allocates a multiport struct but never frees it.
Don't leak memory, free the allocated mpi struct during driver unload.
Cc: <stable@...r.kernel.org>
Fixes: 32f69e4be269 ("{net, IB}/mlx5: Manage port association for multiport RoCE")
